Reinforced concrete spandrel walls are usually constructed monolithically with beams and columns in low story buildings. Such spandrel walls are not only dead loads on the beams, but would behave as a part of structural members, namely beams with walls. Therefore, it is considered that the stiffness and strength of such members are great higher than those of rectangular beams. In this paper, twenty five test specimens, in which the form of cross-section, shear span ratios, wall thickness, longitudinal reinforcement ratios in beam and shear reinforcement ratios in beam and wall were varied respectively, were tested under many alternatingly cyclic loads, and the behaviors on flexural failure were mainly discussed. Load-rotation angle relationships and cracking diagrams were also shown. The important results obtained from this study are that the final failure of these members were brittle compression failure of thin spandrel wall regardless of tension reinforcement ratios in beams and the load-rotation angle relationships after the failure of compression wall were approximately same as rectangular beam.
